The increase in global surface temperatures has changed the frequency and magnitude of socio-natural hazards and extreme weather events. Climate change is reshaping hydrometeorological patterns across the globe, with increasingly pronounced effects in sensitive regions, such as the Amazon. The Amazon Basin is a region of exceptional hydrological, climatic, ecological, and societal importance. Its diverse environments, extending from the Andes to the lowland rainforest and major river systems, are exposed to multiple hazards, including floods, droughts, extreme precipitation, landslides, riverbank erosion, and wildfires. Climate variability and change, land use transformations, deforestation, and infrastructure development can modify hazard processes, exposure, and vulnerability, creating complex and evolving risks.

Understanding these hazards requires moving beyond isolated events to investigate interactions across spatial and temporal scales. Extreme rainfall can trigger flooding, landslides, and sediment transport, while prolonged drought and heat can create conditions that favour vegetation fires and disrupt river navigation and water availability. Such processes may generate cascading impacts on ecosystems, infrastructure, livelihoods, and communities, including indigenous peoples and traditional riverine populations. Therefore, this session aims to bring together researchers and practitioners working on the drivers, dynamics, interactions, and consequences of socio-natural hazards throughout the Amazon Basin.

We welcome interdisciplinary studies combining observations, remote sensing, modelling, and local knowledge to advance hazard understanding, monitoring, forecasting, and risk reduction. Topics include, but are not limited to:
• Drivers of extreme weather events, such as heavy rainfall, prolonged drought, and heatwaves;
• Hydrological hazards, including floods and flash floods, sediment dynamics, river meandering process;
• Geological hazards: riverbank erosion, "terras caídas", gully erosion, landslides.
• Wildfire hazards and their interactions with drought, vegetation, and land use change;
• Compound and cascading hazards, and their spatial and temporal dependencies;
• Hazard monitoring, early warning, forecasting, and modelling using field observations, remote sensing, and emerging analytical methods;
• Exposure, vulnerability, risk assessment, and disaster risk reduction, including the integration of scientific and local knowledge.
